Re: low coherences and learning difficulties

October 27, 2011

Millie,Coherence is a measure of the brain's ability to communicate through a clean, accurate channel between two sites. When coherences in slow frequencies between sites like F3 and F4, C3 and C4, P3 and P4, O1 and O2, which connect at the midline are low, that suggests that something is interfering with the connections. That something may be excessive excitement in the neurons (they won't stop producing bursts of beta, even when there is no task requiring beta) or it may be a physical disruption caused by a head injury or some sort of lesion. In either case, it's likely that performance will be affected.

Sites like F7 and F8, T3 and T4, T5 and T6 don't share a boundary at the midline. They are very far apart (in brain terms), and they have to send their communications either through the corpus callosum or the anterior commissure, so the delay is greater. They tend to have very low coherences

For language processing issues, the original Squash protocol developed by Dan Maust, places electrodes atF7/CP5 in CH1 and F8/CP6 in CH2, squashing all frequencies can be very helpful (Options--2C).Pete

Hello all. I am training and tutoring a 7 year old with learning difficulties. Her TLC assessment shows low coherences in Theta and Alpha at several sites (F3-F4, C3-C4, F7-F8, T3-T4 and T5-T6). Is this a typical pattern for learning problems? I have been squishing the excessive slow wave activity as well as SMR training. She has responded well; however I thought I also should address the low coherences. After adjusting frequencies for her age, I thought I would try F3-F4 and C3-C4 coherence up training. I am also questioning whether training at F7-F8 and T5-T6 would be beneficial as well. Since I heard T3-T4 is too far apart to accurately measure coherence, I question where to draw the line. I would appreciate any suggestions and experience others may have.

Thanks Pete for your insightful explanation.

She does have some language as well as math challenges. I am

tempted to try Dan Maust’s Squash protocol; however am hesitant as she is

very creative and I do not want to squash the Alpha in the back of her head. In

your experience, would referencing CP5 & 6 possibly have a squash effect on

the P sites as well? I look forward to your response and greatly

appreciate the suggestion.

All the best,

Millie

Millie,

Coherence is a measure of the brain's ability to communicate through a clean,

accurate channel between two sites. When coherences in slow frequencies

between sites like F3 and F4, C3 and C4, P3 and P4, O1 and O2, which connect at

the midline are low, that suggests that something is interfering with the

connections. That something may be excessive excitement in the neurons

(they won't stop producing bursts of beta, even when there is no task requiring

beta) or it may be a physical disruption caused by a head injury or some sort

of lesion. In either case, it's likely that performance will be affected.

Sites like F7 and F8, T3 and T4, T5 and T6 don't share a boundary at the

midline. They are very far apart (in brain terms), and they have to send

their communications either through the corpus callosum or the anterior

commissure, so the delay is greater. They tend to have very low

coherences

For language processing issues, the original Squash protocol developed by Dan

Maust, places electrodes at

F7/CP5 in CH1 and F8/CP6 in CH2, squashing all frequencies can be very helpful

(Options--2C).
